Product introduction: Bi-directional No-back clutch SR2

Today we would like to introduce our product bi-directional no-back clutch SR2.


>>Movie

Utilizing SR2, by applying a light touch it is even possible to adjust the height of a heavy object, and to lock the object at any position.

SR2 has two functions which can realize the aforementioned motion:

①To conduct driving from input shaft to output shaft
②To lock the input from the output shaft, if the driving isn’t applied

You can install this lifting and keeping mechanism in applications such as adjustable tables, handicap sinks, and indoor clothes-drying hangers.

TOK has 30+ years' experience of providing one-way clutches/bearings.
SR2 was designed using these technologies, resulting from our customers' requests.

By using our accumulated technology to meet customer requirements, TOK is now developing the new product line “SR series."

We will introduce other SR series products via the newsletter.

Greaseless ball bearings

In the previous blog, we introduced the types of bearings.
For example, bearings are used for drawers, it helps to move smoothly.

Today we would like to explain about the inner mechanism of ball bearing.

Ball-bearings have balls between the inner race and outer race.

This is the difference compared to rollers.
Ball bearings are superior in durability because they receive force at "points" rather than "surfaces".

Lubricating oil or grease is used between the balls and inner race.
If not necessary, we can provide bearings without grease.

Ball bearings with grease
・Pros: High durability
・Cons: Slight rotation resistance occurred

Ball bearings without grease
・Pros: Possible to use in liquid
・Cons: Low durability

In case of TOK products, non-grease type of bearings have "GN" in the product name.

If you cannot find desired products, we can customize all of products according to your requirements, e.g. dimension, shape, material etc.
We can consider which solution is the best for you exclusively.
Please contact us today so that we can work with you.
